Based on the provided knowledge sources, there's no direct information about adding a progress bar inside a table in an MDX file. However, MDX allows you to include JavaScript expressions and custom components within your Markdown. This means you could potentially create a custom progress bar component and include it in your MDX content.
Here's a general idea of how you might do it:
import ProgressBar from './ProgressBar';
## How much Claude 3 models costs?
| Model Name | Context Window | Input Cost ($/million tokens) | Output Cost ($/million tokens) | Progress |
| :----------------: | :------------: | :---------------------------: | :----------------------------: | :------: |
| Claude 3 Opus | 1 Million | $15 | $75 | <ProgressBar value={75} /> |
| Claude 3 Sonnet | 200K | $3 | $15 | <ProgressBar value={15} /> |
| Claude 3 Haiku | 200K | $0.25 | $1.25 | <ProgressBar value={1.25} /> |
In this example, ProgressBar would be a custom component that you've created, and value would be the progress you want to display. You would need to create this component yourself, as it's not provided by Astro or MDX.
